概述

Description

TPS61085PW is a Texas Instruments DC-DC converter designed for battery-powered portable devices. It provides efficient voltage regulation from a low-voltage source to a higher, stable output rail, suitable for compact systems.
Key points:
- High-efficiency power regulator with integrated switching MOSFET (suitable for small handheld circuits).
- External resistor network sets the output voltage; includes enable/shutdown control.
- Protects against fault conditions with undervoltage lockout, current limit, and thermal shutdown.
- Designed for low quiescent current in battery-powered applications; fast transient response.
- Small PW package, ideal for space-constrained boards.
Typical applications:
- Wearables, sensors, handheld electronics, and other portable devices needing a boosted or regulated rail from a single-cell or low-voltage source.
Note:
- For exact input/output voltage ranges, current capability, switching frequency, efficiency, and pinout, consult the TI TPS61085PW datasheet and product page.

Features

TPS61085PW features (typical):
- High-efficiency boost/DC-DC converter for portable apps
- Input range: 0.9 V to 5.5 V
- Output voltage adjustable with external feedback (suitable for 3.3 V or 5 V rails)
- Fixed switching frequency (around 1.0–1.2 MHz)
- Strong low- and full-load efficiency
- Enable/shutdown input
- Protection: overcurrent/short-circuit protection and thermal shutdown
- Internal current limit
- Small 8-pin package with low quiescent current
Note: exact values (e.g., output range, switching frequency) are in the TI datasheet; refer to it for precise specifications and application conditions.

Package

8-pin VSSOP (PW) package.

Pinout

- Pin count: 8 pins (PW package).
- Function: Boost (step-up) DC-DC converter for battery-powered applications. It uses an external inductor (and diode per topology) to convert a lower input voltage to a higher regulated output, with enable/shutdown and feedback for setting the output voltage.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company, headquartered in Dallas, Texas, that designs and manufactures analog, mixed-signal, and embedded processing ICs (including power-management devices).

Application

TPS61085PW is a high-efficiency boost converter for battery-powered portable devices that must raise a single-cell battery voltage to a higher rail. Typical applications: LED backlight/flash drivers; power management for handheld electronics (phones, MP3 players, cameras, PDAs, wearables, wireless sensors); energy-harvesting or backup-power stages in small instruments; any Li‑ion/NiMH-powered system needing a higher regulated output.
